DETAILED DESCRIPTION OF THE INVENTION

Referring to the drawings and initially to FIGS. 1-3, a bottom bedstructure 1 of an electric bed in accordance with the preferredembodiment of the present invention comprises a front bed bottom 10, arear bed bottom 11, two hinge mechanisms 12, and a plurality of stands13.

The front bed bottom 10 includes a first frame 100 and a first board101. The first frame 100 of the front bed bottom 10 is provided with twofirst screw holes 1000, two first mounting seats 1001, and a secondmounting seat 1002. The rear bed bottom 11 includes a second frame 110and a second board 111. The second frame 110 of the rear bed bottom 11is provided with two second screw holes 1100, two third mounting seats1101, and a fourth mounting seat 1102. The fourth mounting seat 1102 ofthe second frame 110 is located opposite to the second mounting seat1002 of the first frame 100 to enhance the stability of the bottom bedstructure 1. Each of the two hinge mechanisms 12 includes a pivotbracket 120 and two bolts 121. The pivot bracket 120 of each of the twohinge mechanisms 12 is provided with two third screw holes 1200 formedin two ends thereof. Each of the stands 13 is provided with a fasteningbolt.

In assembly, the front bed bottom 10 and the rear bed bottom 11 arejuxtaposed to each other. Then, the pivot bracket 120 of each of the twohinge mechanisms 12 is located between the first frame 100 of the frontbed bottom 10 and the second frame 110 of the rear bed bottom 11. Then,the two bolts 121 of each of the two hinge mechanisms 12 extend throughthe two third screw holes 1200 of the pivot bracket 120, the two firstscrew holes 1000 of the first frame 100, and the second screw holes 1100of the second frame 110 respectively, such that the pivot bracket 120 ofeach of the two hinge mechanisms 12 is pivotally connected with thefirst frame 100 of the front bed bottom 10 and the second frame 110 ofthe rear bed bottom 11 respectively. Then, the stands 13 are screwedonto the two first mounting seats 1001, the second mounting seat 1002,the two third mounting seats 1101, and the fourth mounting seat 1102 bythe fastening bolts.

Referring to FIG. 4 with reference to FIGS. 1-3, the stands 13 areremoved from the first frame 100 of the front bed bottom 10 and thesecond frame 110 of the rear bed bottom 11. At this time, the firstframe 100 of the front bed bottom 10 and the second frame 110 of therear bed bottom 11 are connected pivotally by the pivot bracket 120 ofeach of the two hinge mechanisms 12, such that each of the two bolts 121of each of the two hinge mechanisms 12 functions as a fulcrum. Thus, thefront bed bottom 10 is pivoted upward relative to the rear bed bottom11, until a right angle (90°) is defined between the front bed bottom 10and the rear bed bottom 11. At this time, each of the two hingemechanisms 12 is perpendicular to the front bed bottom 10.

Referring to FIGS. 5 and 6 with reference to FIGS. 1-3, the front bedbottom 10 is pivoted toward the rear bed bottom 11, until the front bedbottom 10 overlaps the rear bed bottom 11. At this time, each of the twohinge mechanisms 12 is perpendicular to the front bed bottom 10 and therear bed bottom 11. Thus, the front bed bottom 10 overlaps the rear bedbottom 11, such that the bottom bed structure 1 is folded, to reduce thewhole volume, thereby facilitating storage, packaging and transportationof the bottom bed structure 1.

Referring to FIG. 7 with reference to FIGS. 1-3, the front bed bottom 10is pivoted outward relative to the rear bed bottom 11, until the frontbed bottom 10 is juxtaposed to the rear bed bottom 11, to expand thebottom bed structure 1. Then, the stands 13 are secured to the two firstmounting seats 1001, the second mounting seat 1002, the two thirdmounting seats 1101, and the fourth mounting seat 1102 by the fasteningbolts. Thus, the bottom bed structure 1 is used after expansion.

Accordingly, the front bed bottom 10 is pivoted to overlap the rear bedbottom 11, such that the bottom bed structure 1 is folded, to reduce thewhole volume, thereby facilitating storage, packaging and transportationof the bottom bed structure 1, and thereby decreasing the cost ofpackaging. In addition, the bottom bed structure 1 is expanded andfolded easily and quickly, such that the user expands and folds thebottom bed structure 1 conveniently.
